[Soekris] Powersupply Net4801

[Egbert Jan]

Tnx Bob and others. Having the disk in the 4801 is a nuisance anyway and I
should get rid of it. But installing Vyatta router is easier on disk than on
CF... Pity that you need a disk with less than 0.5 A. I use a standard 2.5"
IBM Travelstar which draws about 0.7. I think I will get a separate external
5V power supply for the time being.

PS Bernd, why have you a high end Matrox card in a 4801??? It just seems not
to match each other...
